Abstract

|
|
|
Labyrinthine fistula refers to a condition caused by an abnormal connection between the inner ear and surrounding structures. Most cases of that occur as a result of a complication brought about by cholesteatoma. It may also be generated by long repeated infections of a mastoid cavity that has been exposed to the outside after canal wall down mastoidectomy (CWDM). The infection is usually repeated for several years or decades after surgery. Therefore, labyrinthine fistula after CWDM is known as a late complication. In this case, labyrinthine fistula occurred in two months after surgery due to postoperative infection. Although cholesteatoma was removed after CWDM and the horizontal semicircular canal (HSCC) was not damaged during the operation, this labyrinthine fistula was thought to develop very early after surgery. Two months after surgery, the patient complained of dizziness, we identified the opened bony labyrinth and damaged endosteum of the HSCC in the patient.
